Journal Club Theme of April 2012: Phononics: Structural Dynamics of Materials
Submitted by mihussein on Sun, 2012-04-01 02:43.Engineering structures are made out of materials and as such there is a natural hierarchy in which a material’s intrinsic properties contribute to shaping up the structure’s response. It is possible however to reverse this hierarchy and engineer materials that are made out of structures. In this case, the intrinsic properties of a material are shaped by the structural response. Such a configuration can only be realized with a repeated structure, forming an array of identical unit cells.

PhD Studentship in Advanced Tomographic Microscopy for Damage Modelling in Steels
Submitted by Daniel S. Balint on Thu, 2011-06-23 16:18.
Imperial College London
Department of Mechanical Engineering
Applications are invited for a research studentship in the field of Advanced Tomographic Microscopy for Damage Modelling in Steels, leading to the award of a PhD degree. The post is supported by a bursary and fees (at the UK/EU student rate) provided by EPSRC. The studentship is for 3.5 years from October 2011 (or to start soon after) and is available for UK and EU candidates meeting the Research Council criterion of having been resident in the UK for the previous three years. The student will benefit from collaboration with Tata Steel, a leading global metal processing company. Tata Steel will also provide a bursary top-up; the total bursary will be approximately £19,000 per year tax-free. The student will also benefit from use of the Diamond Light Source, and interactions with scientists at both the Diamond facility and University of Manchester.
Please read attached advert for further details.

Spectacular torsional-flexural autovibrations of a Volga bridge
Submitted by gregk on Fri, 2010-05-21 22:15.The autovibrations of the bridge over Volga river in the city of Volgograd(Russia) were filmed (not by me) today on 05/21/2010. The amplitude reachedabout 1 m. The bridge opening was just six months ago...
Apparently, either the bridge frame drag was too high or torsional stiffness / damping too low.

The History of Another Dimension - 50 Years of Bentley's V8 Engine
Submitted by Martin Pratt on Fri, 2009-01-23 10:27.Dr Ulrich Eichhorn's lecture covers the original design and development of the Bentley V8 engine, from its introduction in 1959, in their S2 model, through to its present day form in the newly launched Bentley Brooklands coupe.
With contributions from several senior figures involved with the engine's creation and evolution over the last 50 years, the talk will describe how a well thought out concept and its careful execution have carried the design through to 2009, while other contemporaries have long since fallen by the wayside.

How to post a presentation?
Submitted by Teng Li on Tue, 2008-07-08 21:00.Giving presentations at conferences or seminar series is a vital part of a researcher's professional life. Listening to others' presentations is also one of the best ways to stay current with the frontier of a research field. While the audience in conference/seminar room is often limited, a presentation posted online can be virtually viewed by any interested audience. At iMechanica, users have started to post their presentation slides, quite often as the attachments of a post briefing the presentation. Such a way is simple and effective, but may not be the best way for everyone for the following reasons:

An interesting coupling
Submitted by Biswajit Banerjee on Wed, 2007-06-13 04:36.A video that shows how some common couplings work. It's an advertisement but interesting nevertheless. Does anyone know how the Thomson coupling works and what its main drawbacks are? It seems a bit complex and will probably have a higher rate of failure than simpler geometries - but maybe not?
